Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

WHILE EN ROUTE ON A DARK NIGHT, THE AIRCRAFT COLLIDED WITH MOUNTAINOUS TERRAIN IN A HEAVILY WOODED, SNOW COVERED AREA. AN INVESTIGATION REVEALED THAT THE PLANE CRASHED WHILE IN OR NEAR LEVEL FLIGHT AT AN ALTITUDE OF ABOUT 4500 FT MSL. THE TOP OF THE MOUNTAIN WAS ABOUT 5200 FT. THERE WERE BROKEN AND OVERCAST SKY CONDITIONS WELL ABOVE THE ALTITUDE OF THE CRASH SITE. THERE WAS NO MOON ON THAT NIGHT AND THE CLOUDS WOULD HAVE BLOCKED OUT ALL REFERENCE TO THE SKY. ALSO, THERE WERE NO KNOWN GROUND REFERENCE LIGHTS IN THE AREA OF THE ACCIDENT.
